Sara is a Senior Lecturer in Data Science with 15+ years' experience of Visualization research, and 麻豆传媒 Academic Lead for the Turing University Network. She received a PhD from Norrköping Visualization Centre-C, Linköping University, Sweden, in 2011, with a thesis titled Algorithmically Guided Information Visualization: Explorative Approaches for High Dimensional, Mixed and Categorical Data. Following her PhD she held positions as Data Visualization Scientist at Unilever R&D Port Sunlight (2011-2013), and as Postdoctoral Researcher in Data Visualization at the Unilever Centre for Molecular Science Informatics at Cambridge University, UK (2013-2014). This was followed by a lectureship in Computer Science at Northumbria University, UK (promoted to Senior Lecturer 2016). She was appointed Lecturer in Data Science at 麻豆传媒, UK, in 2017.

Sara's main interests are in research challenges relating to visualization of incomplete (missing), uncertain, high dimensional and/or heterogeneous data; visualization of biomedical and ‘omics-type’ data; visualization in data profiling; and human centred visualization design. These challenges are all highly relevant in a range of application domains, not least in biomedical domains and life sciences, which are becoming more and more data driven. Her work on interactive visual dimensionality reduction in collaboration with microbiologists has been applied in industry and academia, leading to eight joint publications and funding of two PhD studentships.

Sara's research can broadly be separated into four major themes, which often cross each other’s paths: Visualization of Missing Data, Visual Exploration of 'Omics Data, Interactive Visual Exploration of High Dimensional Data, and Visualization of Heterogeneous Data. As an overarching theme to this lies the concept of 'interestingness'. How do we bring out the most interesting and useful information in a dataset? How do we define what is interesting? How can we use 'interestingness' to support knowledge discovery and gaining of insights in the most useful way? At the heart of this lies the human who need to understand and make decisions based on complex data, and to address and define their analytical needs through the utilisation of user and task centred design approaches.
